Used on over 1.6 million roofs worldwide, Sky Products uses S-5!® clamps to attach snow retention  and solar systems to the panel seam. The clamps attach to the seam by the tightening of two “bullet –nosed” stainless steel setscrews against the seam material.  The round point setscrews compress the seam material against the opposite wall of the clamp. They will “dimple” the seam material, but will not penetrate it.

S-5!® clamps are made from 6061-T6 aluminum extrusions conforming to ASTM B221 or aluminum castings conforming to ASTM B85 and to AA Aluminum Standards.

The setscrews are made from 300 series stainless steel, 18-8 alloy.

Why Sky Products chose S-5! ® products

Are they strong enough? 

In order to promote the best non penetrating clamping system S-5! ® has performed hundreds of tensile-load tests to prove the holding strength of the clamps. All tests were performed by a third party A2LA accredited laboratory, all results are available online.
